GtkIconSource* gtk_icon_source_new ( void )
Creates a new
GtkIconSource contains a
image filename) that serves as the base image for one or more of the
icons in a
GtkIconSet, along with a specification for which icons in the
icon set will be based on that pixbuf or image file. An icon set contains
a set of icons that represent “the same” logical concept in different states,
different global text directions, and different sizes.
So for example a web browser’s “Back to Previous Page” icon might
point in a different direction in Hebrew and in English; it might
look different when insensitive; and it might change size depending
on toolbar mode (small/large icons). So a single icon set would
contain all those variants of the icon.
GtkIconSet contains a list
GtkIconSource from which it can derive specific icon variants in
In the simplest case,
GtkIconSet contains one source pixbuf from
which it derives all variants. The convenience function
gtk_icon_set_new_from_pixbuf() handles this case; if you only have
one source pixbuf, just use that function.
If you want to use a different base pixbuf for different icon variants, you create multiple icon sources, mark which variants they’ll be used to create, and add them to the icon set with gtk_icon_set_add_source().
By default, the icon source has all parameters wildcarded. That is, the icon source will be used as the base icon for any desired text direction, widget state, or icon size.
